OMNI Power Plug and Play 3 Bar Map Sensor Fits 2004-2007 STI

Omni Power USA 3 Bar MAP (Manifold Absolute Pressure) sensors use state-of-the-art bipolar op amp circuitry with thin film resistor networks built into each microchip. Pressure changes are calculated on a true linear 0-5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows the Omni Power USA 3 Bar MAP sensor to remain a minimum of 99% accurate from 32 degrees F to 180 degrees F throughout its range of scale. With the true linear pressure vs. voltage scale, there is never a need to re-tune at different altitudes as with other sensors. Other sensors on the market don't have true linear scaling, which can cause your engine to go out of tune with elevation changes, often resulting in idle problems, poor drivability, and catastrophic engine damage.
